## Conversion formula

The conversion factor from feet per second to kilometers per hour is 1.0972799999991, which means that 1 foot per second is equal to 1.0972799999991 kilometers per hour:

1 ft/s = 1.0972799999991 km/h

To convert 555 feet per second into kilometers per hour we have to multiply 555 by the conversion factor in order to get the velocity amount from feet per second to kilometers per hour. We can also form a simple proportion to calculate the result:

1 ft/s → 1.0972799999991 km/h

555 ft/s → V(km/h)

Solve the above proportion to obtain the velocity V in kilometers per hour:

V(km/h) = 555 ft/s × 1.0972799999991 km/h

V(km/h) = 608.99039999951 km/h

The final result is:

555 ft/s → 608.99039999951 km/h

We conclude that 555 feet per second is equivalent to 608.99039999951 kilometers per hour:

555 feet per second = 608.99039999951 kilometers per hour
